drivers: convert shrinkers to new count/scan API
does not contain lowmem_shrink(), but lowmem_scan() instead. plus at lest
one more patch on top of it (e2bfaf75e763396b7baa7c1effa4053d7f19e6d3):
-static int lowmem_shrink(struct shrinker *s, struct shrink_control *sc)
+static long lowmem_scan(struct shrinker *s, struct shrink_control *sc)
wouldn't it be better to have the patch against -next in this case (in
case it fixes anything)?
